Application ille'd August 26, 1812. Serial Nb. 717,168.

To all whom it may concern Be it known that I, ISRAEL A. ltosl-ron, a citizen of the United States, residing at Worthington, in the county of Nobles and State of Minnesota, have invented certain new and useful Improvements in Attachments for Linotype-hilachines, of which the following is a specification.

This invention is an attachment to a linotype or slug casting machine, designed to maintain at all times a certain amount of metal in the metal pot by feeding thereto a single old slug after the removal of each charge of metal for the casting of a new slug. By this means as suliicient metal is removed from the metal pot to cast each slug a like amount of metal in the form of an old slug is fed into the metal pot to make up for the amount that has been taken out.

To these ends the invention consists genorally in the constructions and combinations hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification; Figure 1 is a side elevation, partiali'y in section, of a linotype metal pot, and means for holding and moving the same with my newly invented slug feeding device attached thereto. Fi 2 is a rear elevation of the parts shown in l ig. 1, Fig. 3 is a detail showing the construction of the slide operating rod, Fig. 4: is a detail section of the slug holder, Fig. 5 is an elevation showing a portion of the frame of the machine and means for securing the slug holder thereto, Fig. 6 is a transverse hor1- zo'ntal section of the slug holder, Fig. 7 is a side elevation thereof.

In the drawings, 2 re resents the metal pot of a linotype or simi ar machine, which is supported by suitable arms 4 upon a shaft 3.

5 is the slug ejector arm, which, in the machine, is given a rockin motion to operate the ejector slide (hnot s own) which ejects from the mold 'eac new slug after the same is cast.

I have not shown the means for forcing the liquid metal from the metal pot into the mold, or the mold itself, or the means for ejecting the slugs therefrom as they are cast, as these parts are common to all linotype machines and in themselves form no part of my invention. It will be under stood, however, that my invention is attached to the metal pot or other suitable part of the linotype machine, and that its reciprocating slide hereinafter referred to is operated to correspond with the operation of the linotype machine in the casting of each slug from metal removed from the metal. pot.

In the articular embodiment of the invention il ustrated in. the drawings and described in the present specification, the movable ejector arm of the linotype machine, which causes the slugs to be successively ejected from the mold in which they are cast, is used as a means to which the feeding slide, hereinafter described, is connected and by which it is operated. Any other movable part of the linotypc machine which moves at, or immediately before, or after, the casting of a new slug from the metal discharged from the metal pot, may be employed to move the feeding slide hereinafter referred to.

A light frame 5 preferably formed of metal supports the parts of the feeding mechanism. it is secured to the metal pot by suitable arms 6. At its upper end it carries a horizontal table 7 secured to said frame by any suitable means, which may include suitable braces 8, and having near its forward end an opening or slot 9 above a chute 10, which leads from the opening 9 in the table 7 to the metal pot, so as to be capable of discharging into said pot. The table 7 is preferably provided with guide-ways or grooves 11, and a distributing slide 12 is arranged upon said table with its edges pr0 jecting into said grooves. Said slide is capable of being reciprocatcd upon said table, being guided by the engagement of its edges with said grooves. An arm 13 is c0nnected to said slide and a connecting rod engages the arm 13, and has its opposite end connected preferably by a yoke 16 with the free end of the ejector arm 5. As here shown the connecting rod is made up of three parts, the rod 17 having the yoke or hook 16 at one end which engages with a pin 5' on the ejector arm 5 and carries at its opposite end a nut 18; a rod 19 that is connected at one end directly to the arm 13 and has its opposite end screw threaded, and a turn buckle 20 into one end of which the rod 19 is screwed, while the rod 17 projects through the opposite end of said turn buckle and is provided with a spring 21, which surrounds said rod 17 and bears at one end upon the bottom wall of the socket of the turn buckle, and at its other end upon the nut 18. This construction furnishes an extensible connecting rod, which may be lengthened or shortened at any t-ime'by turning the turn buckle 20 and thereby moving the threaded end of the rod 19 out of or into the threaded opening in the end of said turn buckle.

The slide 12 is provided with an opening 12 (see Figs. 1 and 1) which is of sufficient size to receive a single slug therein.

Rising from the frame of the machine are the posts or standards 25, 25, connected by the transverse bars 26 and 27, each of which is provided with a slot 28 and through which slot extends a bolt 29. These bolts are provided with thumb nuts 30.

A slug holder 31 is placed vertically upon the machine frame and is secured in position by means of the bolts 29 which pass through holes in the back plate of the slug holder 31 and through the holes 28 in the cross bars 26 and 27. By means of the bolts 29 and the nuts 30 the slug holder can be clamped to the cross bars 26 and 27, and the elongated form of the openings through which the bolts 29 pass permits of a certain amount of vertical adjustment of said slug holder in reference to the table 7 and slide 12. The other portion of the slug holder is in the form of a rectangular open trough 32 in which the used slugs may be placed. This trough is preferably provided with a cross pin 33 near the end thereof that becomes the lowermost end when the device is in position in the machine and which holds the slugs in the trough when said trough is placed in a vertical position. The slug holder section 32 may be secured in place on the back section 31 by means of suitable hooks 34 (see Fig. 7). The end of the trough section 32 of the slug holder which is to be uppermost when the device is in position in the machine is provided with an end plate 35 having a hook 36 at its end and this hook is adapted to hook over the other end of the back section 31 when the slug holder is in place in the machine. (See Fig. 1.) When the slug holder is in position in the machine as shown in Figs. 1 and 2, one end will be directly over the opening 12 in the slide or plate 12 and when said plate is in its retracted or receiving position the opening in the plate will register with the opening through the slug holder and the lowermost slug on the carrier will drop into the slug opening in said plate and will rest upon the upper surface of the table 7. (See Figs. '1 and 4'.) Then, as the slide 12 is moved forward, after each new slug is cast or is ejected from the machine, the lowermost slug in the stack which is within the opening in the slide will be moved forward until it comes over the opening 9 in the plate 7. It will then drop into the chute 10 and passing down said chute will fall into the metal' pot, thereby supplying the said pot with the same amount of metal that has been removed for casting the new slug. 1 also prefer to provide on the outer wall of the slug holder a suitable bell 35 with a hammer 36, having an end that projects through a slot in the wall of the slug holder, in posit-ion to be engaged by the slugs therein. (See Fig. 4:.) When the slugs in the holder have become exhausted the end will be released and will fly upward permitting the hammer to strike the bell to call the attention of the operator to the fact that a new supply of slugs is needed in the holder.

l[ have shown the device attached to the metal pot of a so-called junior linotype machine, but it will be understood that ll am not limited to its application to any particular style or type of machine. llt may be used in connection with any slug casting machine.

In the operation of the ordinary linotype machine most operators, either through negleet or forgetfulness, fail to feed the metal to the metal pot regularly as required, and,

in consequence, cast a number of honey combed or bad slugs before their error is discovered, or if too much metal is fed at a time they cast cold slugs with a bad face, which are just as worthless, thus causing great annoyance and a loss of much valuable time. With my automatic metal feed this trouble is overcome or reduced to a minimum. When the metal is once at the proper temperature and temper, with the burner adjusted properly, other than placing a galley in position when required, the machine needs very little or no attention as the automatic feed always replaces the metal or slug one at a time as fast as the hot metal is taken from the pot, thus enabling the operator to give full attention to the keyboard with knowledge that his slugs are always being cast in good condition. With this attachment the same amount of metal always remains in the metal pot, and with the burner properly adjusted will always remain at practically the same temperature.

The device, it will be noted, is composed of four separate detachable parts which can be easily adjusted to any linotype machine without in any way marring or defacing the same.

Changes in the details of construction may be made without departing from my invention.
